BreakVector — decompose FVector into X Y Z

BreakVector2D — decompose FVector2D into X Y

BreakHitResult — decompose hit result structure into components

UGameplayStatics::BreakHitResult. Most important outputs: bBlockingHit, ImpactPoint, ImpactNormal, HitActor, HitComponent.

BreakRotator — decompose FRotator into Roll Pitch Yaw

UKismetMathLibrary::BreakRotator. NOT BreakRot.

BreakTransform — decompose FTransform into location rotation scale

DestroyActor — remove actor from the world

Respawn system: death → delay → respawn at PlayerStart

In Character BP: OnDied (custom event) → SetActorHiddenInGame(true) → SetActorEnableCollision(false) → Disable input: GetController → DisableInput → Delay(Duration=3.0) → GetGameMode → CastTo<BP_GameMode> → RestartPlayer(GetController) → SetActorHiddenInGame(false) → SetActorEnableCollision(true) → EnableInput. In GameMode RestartPlayer: Gets nearest PlayerStart → SetActorLocation to PlayerStart → calls OnPossess. OR manual: GetAllActorsOfClass(PlayerStart) → Random select → SetActorLocationAndRotation(PlayerStart.Location, PlayerStart.Rotation).

SetLifeSpan — set actor lifetime before auto-destroy

0 = live forever.

Health regeneration over time with timer

Pattern: Variables RegenRate(float)=5.0, RegenDelay(float)=3.0, RegenTimerHandle. On damage received: ClearTimer(RegenTimerHandle) → SET timer(RegenDelay, RegenTick, looping=true). RegenTick function: Branch(Health < MaxHealth) → True: SET Health = FClamp(Health + RegenRate*DeltaSeconds, 0, MaxHealth). False: ClearTimer.
